David Holden will head to the general election this November, after winning his primary race for the U.S. House seat.

Holden received 67.9 percent of the vote over Todd Truax in the first Democratic primary in decades for the overwhelmingly Republican District 19. The district includes Cape Coral, Fort Myers, Bonita Springs and Naples.

Holden has the unenviable task of trying to unseat U.S. Rep. Francis Rooney, R-Naples. Rooney was first elected to the House in 2016, when he received 64 percent of the votes in Lee County and 71 percent in Collier.

Holden raised about 33 times as much as Truax in individual campaign contributions — $247,000 compared to less than $8,000 — according to federal campaign finance data.

Both Democratic candidates highlighted health care as their main focus, and Holden highlighted his upbringing by activist parents, his commitment to serving others and his willingness to work across party lines at a voter forum earlier this month.

Holden, a Wells Fargo financial adviser with a degree from Harvard, moved to Naples about three years ago from San Francisco. He said he decided to run almost immediately after the 2016 election.

He said the Trump administration is “determined to destroy health care in this country” and that it’s the most important issue facing Americans.

“I believe in the richest country in the history of the world, health insurance is a fundamental human right,” Holden said. “We have to make sure that we provide every American with not just insurance or access but the reality of quality health care.”
